The letter notes lawyers for the White House and OGE spoke on Feb. 9 — the day of Conway's interview — and that the Republican and Democratic leaders of the House Oversight Committee asked OGE to follow up.

White House spokesman Sean Spicer said last week that Conway has been "counseled," but the OGE said it has yet to receive any guidance on what if anything happened as a corrective action. The OGE is requesting that White House lawyers tell them in writing by Feb. 28 what they've done about the matter.
